The United States is "much better prepared" now than it was at the time of the 9/11 attacks, but it's important to remember the country is still in danger, Rep. Pete King said Tuesday.

"We have tremendous cooperation at all levels of government and much greater cooperation with friends, allies, and countries that have to cooperate with us for their own selfish reasons," the New York Republican told Fox News' "America's Newsroom."

Still, King said, it's important to remember that "Al Qaida, ISIS, and others still want to kill us every day of the week. That's why it's so important we not be politically correct, we do what we have to do, constantly monitor what Islamist terrorists are trying to do."

The United States has adapted, said King, and has "probably guaranteed" there will never be another 9/11, but "we can't give in to political correctness or we could see another 9/11 type attack in a different form but have the same result."

Meanwhile, downtown Manhattan has made a remarkable recovery in the years after the attacks, he said.

"I remember being here with President [George W.] Bush three days after 9/11 and it was impossible to believe it would ever come back," he said. "I think so much is owed to the police and firefighters, construction workers who did so much on 9/11 and the days after. That was an inspiration to all the people."
